Simple 1st test might be to check Battery Voltage to see if there is enough to make ECU "Happy" ~

With key on are you actually getting power to the ignition coil, which also goes to the ECU? Need a meter ensure it is close to battery voltage.
> While engine is cranking do you get spark? You should see the tach move slightly but better to check at coil. No spark due to primary failure will also mean no fuel pump. After all is checked out you have a separate ignition module and the distributor pick up coil, (Hall sensor) are possible failure items. So is the ECU. From the fuel pump relay there is a separate harness to the pump and there is a connector near the air filter. You can use that harness to directly power the pump for testing.
